London Welsh were comfortable winners of last week's first leg

3:10 pm

With London Welsh undoubted favourites to secure promotion this evening, Bristol chairman Chris Booy has issued a rallying call to his side.

He said: "I absolutely believe. I see no reason why we can't win the match and win the tie. There's absolutely no doubt in my mind.

"The guys are angry and they feel as if they let everyone down in the first leg. But they are ready for Wednesday and they are confident.

"If we remember the last time we played London Welsh at the Memorial Stadium, we put in a very, very strong performance and led 22-0. It was only right at the end of the game, when we turned off, that they came back into it.

"We need to score early. We don't need to panic, but we need to score first, and all of a sudden it's a 12-point game. Throw in the atmosphere the crowd will create – which I know will be amazing – and you never know.

"We are not stupidly confident or over-confident – we know there's an awful lot to do. But we believe we can do it."

As we move away from Wales' upcoming trip to South Africa, let's focus on London Welsh for a second.

They've got a massive game against Bristol at the Memorial Stadium this evening in their Championship final second leg.

The Exiles have a 19-point lead over their opposition and know a win or a defeat by less than 19 would take them back to the Aviva Premiership.

We'll be covering tonight's game live here at WalesOnline so stay tuned for that...

Our man Simon Thomas has some injury news this luncthime...

Great to hear that @cardiffblues centre Owen Williams is coming along well in his recovery from persistent hamstring trouble. A real talent.

South Africa head coach Heyneke Meyer on the side he has picked to face the World XV.

"It’s positive to have this kind of continuity in our first start of the year.

“Even though we’ll be starting with a new midfield combination, Frans and JP have both played more than 50 Tests for the Boks and with Bryan Habana also in the backline, Cornal will start with a lot of experience around him.

“We’re expecting a stern test on Saturday against the World XV and our mindset is to make our nation proud – it should never be anything else when the Springboks play.

"It will also be a good way to start the season before our first Test next week against Wales, but for now we’re only focused on the World XV and playing well.

“Our aim for the season is to accelerate and make a step up from 2013. To put ourselves in a position to do that, we simply have to start well.”

South Africa have named their side to face the World XV this Saturday ahead of their first Test against Wales a week later on June 14.

South African sevens star Cornal Hendricks will make his debut in the 15-man code on the wing while JP Pietersen moves to outside centre.

The old firm of Bakkies Botha and interim captain Victor Matfield are re-united in the second row. Schalk Burger makes a return to the side for the first time in two and a half years while Frans Steyn, Schalk Brits, Lwazi Mvovo and Johan Goosen are also back after playing no Test rugby last year.

He says: "They're a big physical team and they like to go to the air. If picked, I'll have to be on top of my game to take those high balls.

Referring to his short-lived appearance in a brutal encounter against the Boks at the Millennium Stadium in the autumn, Williams added: "I'll stick my body on the line and hopefully last more than 12 minutes."

Meanwhile maintaining the animal theme, Victor Matfield has proved there's life in the old dog yet by being named captain of the Test side to face Wales after a two-year hiatus from the side altogether.

Matfield is 37 and this week we have taken a look at some of rugby's oldest captains...
